Visualizing greenhouse gas emissions

«Even for experts and scientists, analysing data on emissions and climate change can seem like a rising sea of numbers. The United Nations Climate Change Secretariat (UNFCCC) in collaboration with several Googlers has created a map that visualizes greenhouse gas (GHG) emissions generated by a number of industrialized countries.
We hope that this can provide a valuable tool for understanding climate change leading into the upcoming negotiation of a new climate change agreement in Copenhagen at the end of this year.»
